HERMAN N. RODEN, OF MILWAUKEE, WISCONSIN.

BUCKLE.

Application filed April '27,

To all whom it may concern:

Be it known that I, HERMAN N. ltonnN, a citizen of the United. States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Buckles, of which the following is a specification.

My invention relates to improvements in one piece buckles.

The object of my invention is to provide a form of" buckle particularly adapted to engage the canvas shoulder straps of overalls.

Another object of my invention is to provide a form of construction, in which the shoulder strap will be so interlocked with the buckle that it may be securely held without any necessity for having the buckle provided with projectingpoints to pierce the strap, or with teeth, such as are usually em ployed, and which tear and break the threads of the'fabric of which the shoulder strap is composed.

A further object of my invention is to provide a form of construction which can be readily stamped from a single piece of sheet metal in a single operation, which, being integral, requires no subsequent assembly operations, and has no parts to become disengaged in use.

A further object of my invention is to provide improved means, whereby my buckle may be engaged with the button of a button supporting strap, in such a manner as to make the accidental release of the button virtually impossible, and also in such a manner that a person with lingers stiffened by the cold, may readily engage and diselr gage the button with the buckle.

I11 the drawings:

Figure 1 is an elevation of my improved buckle, as it appears in use.

Fig. 2 is an elevation of the same, with the straps removed.

Fig. 3 is a sectional View, drawn on line 3 of Fig. 1.

Fig. 1 is a sectional view, drawn on line 4-4 of: Fig. 2.

Like parts are identified. by the same reference characters throughout the several views.

My improved buckle is formed from a singlepiece of sheet metal, slitted transversely, intermediate of its side margins, to form the frame bars 1 and 2, and a central cross bar 3, each integrally connected with end bars at and 5. At the ends of each of sp fi t of Letters m me Patented June 29, 1920.

1918. Serial No. 231,088.

the intermediate transverse slits vertically disposed slots '7 are formed, and the material between the ends of these slots, on each side of the slit,is bent in opposite di rections to form the oblique lips S, 9, 10. and 11 respectively. The liree margins of each of these oblique lips terminate in right angle corners at the ends adjacent to the slots 7.

A plate or piece of sheet metal, from which my improved buckle is formed, is provided along one side margin with a projecting car 14, having a central aperture 15. themargins of which are provided with recesses on opposite sides, constituting notches 16 and 17, 18 and 19 respectively; the notches 18 and 19 being opposed in a transverse line across the ear, and the notches 16 and 17 being opposed in a longitudinal line, 2'. 6., a line parallel with the end bars 4. and 5 of the buckle proper. The distance from the base of one of these notches to the base of an opposing notch, is just suflicient to allow manipulation of a button 22 through the opening, when the button is turned so as to present its edge across the central p01 tion. of the opening, and into one of the sets of opposing notches. r

It will, of course, be understood that the button 22 will be secured to a cooperating piece of fabric, shaped to constitute a tongue or strap 23 secured to the apron portion of the garment, in a well known manner. By providing two sets of opposing notches at right angles to each other, it is obvious that when the button is brought into position at the rear, or along the inner face of the lip 14, it may be easily tilted, and engaged in the opening, after which it may be readily manipulated through the notches, even though the fingers of the user are stiff with cold. Any engagement of the edge of the button in the aperture will facilitate adjusting it into a position to pass through one set of notches or the other, without making it necessary to turn the button to any great extent. After the button has been passed through the notches, it will, of course, tend to move downwardly until its connection with the strap 23 will be locked in the lower notch 17 and in this position the button will be securely held against accidental disengagement. But it may be readily disengaged by manually tilting it, and manipulating its side margins through the notches.

In use, the buckle is applied to the shoulder strap 25, and the latter manipulated through it, the strap passing first between the flanges S and 9, then around the margins of the lip flanges 9 and 10 011 the outer face of the buckle, and then between the flanges 10 and 11, and downwardly over the margin of the lip 11 along the inner face of the car 14, as indicated in Fig. 4, and as also shown in Fig. 1. After the strap has been thus passed through the opening between the lip flanges 8 and 9, 10 and 11, a pull in either direction upon the strap will draw it tightly across the margins of each of said flanges, and the side margins of the strap 25 will be turned, or partially folded, across the corners of these flanges at the respective ends thereof. \Vhere the width of the strap is sufficient to cause its margins to engage the outer margins of the slots 7, the pressure of these margins upon the .edges of the strap will greatly facilitate turning the edges of the st *ap toward the plane of the buckle plate, thereby folding the strap adjacent to these edges, across the comparatively sharp corners at the ends of the lip flanges.

lVith the above described construction, I am enabled to provide a one piece buckle which will not tear, cut or break the threads of the fabric composing the strap 25, and which will have no detachable parts to become loose or destroyed. But the strap will be securely held against any tendency of the buckle to slip lengthwise thereof after the strap has once been pulled into forcible engagement with the lip flanges. To readjust the buckle along the strap, however, it is merely necessary to lift the free end and push it through the opening between the lip flanges 10 and 11, until a loop of sufiicient size has been provided, to allow the strap to be also pushed from the direction of its free end, and the loop, thus formed, through the opening between the flanges 8 and 9. As soon as this is done, the strap will have no binding pressure upon any of the flanges, and by keeping itlfree from such pressure it may readily be manipulated through the openings in either direction.

I claim:

1. A one piece buckle comprising a piece of sheet metal, transversely slitted to form parallel side bars and an intermediate central bar, integrally connected at their respective ends, said strip of metal being also provided with short slots extending across the ends of the slits, and the material between the slots and along the slits being bent in opposite directions on opposite sides of each slit, to form a pair of substantially parallel "inwardly and outwardly extending oblique flanges, the separatedmargins of which are located substantially in a plane at. right angles to the plane of the unslitted portion of the plate.

2. A buckle formed as set forth in claim 1, in which one side margin is provided with an integrally extending ear, provided with a notched aperture, through which a button may be manipulated and allowed to drop with its shankengaged in one of the notches.

In testimony whereof I allix my signature in the presence of two witnesses.

HERMAN N. RODEN.
